When is earthquake season?

There is no such thing as “earthquake season.” Earthquakes happen in cold weather, hot weather, dry weather, and rainy weather. Weather, which takes place above Earth’s surface, does not affect the forces several miles beneath the surface, where earthquakes originate. The changes in air pressure that are related to the weather are very small compared to the forces in Earth’s crust, and the effect of air pressure does not reach beneath the soil.
